Quick analysis of the correlation between vaccination and death rates of COVID-19.

Correlation between vaccination and COVID-19 reported deaths

Data gathering

• Worldmeters
• Google vaccination statistics

Data cleaning

• removed countries with missing data
• removed countries with invalid data (more than 100% percent vaccination or other errors like this)
• converted per million metrics to per cent metrics

Details

• correlations are calculated using Pearson's coefficient
• there are about 100-120 analyzed countries in the final results

Results

It seems that after the threshold of 20% complete vaccination, a negative correlation between deaths and vaccionation rate occurs.
